How can I flip between two UIView?

Question

I'm using two UITextView objects. Each UITextView represents the side of a single card in a flash card application. Just like when using regular flash cards, I want the user to have the ability to flip a card. I am asking how to flip between two UIView objects because UITextView are UIView subclasses so the same idea should work.

The animation I am looking for looks like this.

The only problem with the above example is that it utilizes two UIViewController objects and UITextView is not a subclass of UIViewController so the same principle does not apply.

Any ideas on how to do the flip animation?

You can use the UIView class method +transitionFromView:toView:duration:options:completion: to accomplish this. Both your text views need to be descendants of a common superview. Use the option UIViewAnimationOptionTransitionFlipFromLeft (or ...FromRight) to get a horizontal flip.
